FEEDING MECHANISM-FOR ovERsEAMINe cur-rEEnMAcHINEs. I

T 'aZZ whom it may] concern Be it known that I, LANSING ONDERDONK, acitizen of the United States, residing at New York, in the county of NewYork, State of New York, have invented certain new and usefulImprovements in Feeding Mechanism for Overseaming Cup-Feed Machines, ofwhich the following is a description, reference being had to theaccompanying drawing, and to the letters and figures of reference markedthereon. a

My invention relates to improvements in overseaming machines, andparticularly to those known in the art as cup feed machines, and in itspresent embodiment; is an improvement on the feeding devices of the ma-1 chine of this character illustrated. in my application filed August4th, 1910, Serial 1 the usual manner, and controlled :by the No.575,589. v I

The object of the present invention isto provide a feed device in whichthe" outer feed member is operated from above, so as to leave anentirely unobstructed space below the engaging point of the two feedcups, whereby the machine is adapted for the sewing of heavy garments,such as sweat- W ersand the like, the bodythereof being ,suspended fromthefeed cups. The invention, therefore, consists in the mattershereinafter described and referred to in the appended claims.

The invention is illustrated in the accom panying drawings, inwhich 1Figure 1 is a side elevation of a portion of an overseaming machine,showing my feeding mechanism; Fig 2 is .a front View;

Fig. 3 is a top plan View; and Fig. 4 a detail sectional view of theouter feed cup and the gearsfor operating it.

V In these drawings is shownanportion.ofg'

the frame 1 of the sewing machine illustrated in my aforesaidapplication. I

In these drawings, 1 represents the inner feed, disk or cup mounted onthe upright shaft2 journaled in a bearing sleeve3 on the main frame, andengagedat its lower end by the friction grip device 4 and operated inthe maimer set forth in my aforesaid application.- Above its lower endthe shaft His provided with agear wheel 5,

which meshes with and drives a gear wheel 6 secured to the lower end ofthe vertical shaft '7, journaled in bearing lugs 8 on the interior ofthe frame or casing 9. This shaft 7 extends above the casing. and on itsSpecification of Letters gate nt.

so that heavy P tented. May a, tars.

upper endhas a'belt wheel which is trained around a similar wheel 12 onthe'upper end of the vertical depending shaft 18; This verticaldepending shaft carries on its lower end the gear wheel 14, which;through an intermediate gears15 drives the gear 1.6 to which the outerfeed roll;:disk or cup 17 is secured. Theouter feed roll, its operatinggearsand thesshaft 13,

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. In a sewing machine, a feeding mechanismincluding inner and outerfeed rolls or disks, a. depending framepivotally supported above themeeting edgesof said rolls or disks and having means for supporting saidouter feed roll or disk, and means -for positively driving said outerfeediroll or disk.

2. In a sewing machine, a: feeding mechanism including inner and outerfeed rolls or disks, a depending frame pi'votally supported above themeeting edges ofsaid rolls or disks and having means for supporting saidouter feed roll or disk, means for driving said innerfeed roll or disk,and positively connecting said inner'feed roll or disk to the outer feedroll or disk, whereby feed rolls or disks are operated in unison.
